During commissioning, a timing program can be created within the block to manage all air conditioner controls at specific times or dates. When the VRF system is set to a particular value or control at these scheduled intervals, it effectively locks those settings. The outputs of these locked controls can be displayed on the UI as status information.</p><p>The lock states are only visible within the <strong>VRF Basic</strong> interface, which can be accessed by enabling the “Show VRF Page” option from the <strong>Settings / System</strong> menu.</p></td></tr><tr><td><img src="/files/O6G2VrkFHSGLnIdCmFSO" alt="" data-size="original"></td><td><strong>Schedule</strong></td><td><strong>The schedule</strong> activates according to the time and frequency defined within the block. It can also be manually triggered using the trigger object if needed.</td></tr><tr><td><img src="/files/c4vYVIlubnadXSZmRHOL" alt="" data-size="original"></td><td><strong>Delay</strong></td><td><strong>The Delay</strong> is a time control block that delays the input command by the specified time in milliseconds.</td></tr></tbody></table>
